CAD vs CAM
CAD thiab CAM yog cov cuab yeej tseem ceeb hauv kev tsim thiab tsim khoom. Ua ntej lub advent ntawm computers thiab tshwj xeeb tshaj yog PC nyob rau hauv lub eighties, draftsmen ua lub luag hauj lwm tseem ceeb nyob rau hauv tsim nyob rau hauv cov tuam txhab. Tab sis computers hloov qhov scenario kiag li. Lawv tus nqi pheej yig thiab ntau yam tau tso cai rau cov engineers los ua cov qauv ntawm lawv tus kheej. Niaj hnub no kev kos duab rau kev tsim qauv tau dhau los ua tsis tiav thiab cov hnub ntawm compasses thiab protractors tau dhau lawm. CAD thiab CAM yog cov ntsiab lus tseem ceeb hauv kev tsim thiab tsim khoom thiab xa mus rau Computer Aided Design thiab Computer Aided Manufacture feem.
CAD
CAD yog siv cov khoos phis tawj los tsim cov lus yooj yim. Nws tseem hu ua CADD, uas sawv cev rau lub khoos phis tawj pab tsim thiab kos duab. Hauv CAD, ntau yam cuab yeej siv computer siv los pab engineers, architects thiab lwm tus kws tsim qauv hauv lawv cov haujlwm tsim.
Keeb kwm CAD xa mus rau lub khoos phis tawj pabcuam kev tsim qauv raws li nws yog qhov hloov pauv ntawm pawg thawj coj ua qauv. Tab sis niaj hnub no nws yog hu ua tsim kom muaj kev cuam tshuam qhov tseeb tias ntau npaum li cas tuaj yeem ua tau nrog kev pab ntawm cov khoos phis tawj dhau li ntawm kev kos duab. CAD feem ntau yog ua haujlwm thaum kev tsim qauv yooj yim tsis tuaj yeem ua txoj haujlwm xws li hauv kev tsim tsheb, dav hlau, nkoj thiab lwm yam qauv tsim.
CAM
CAM yog kev siv cov cuab yeej siv computer uas pab engineers, cov cuab yeej thiab cov neeg tsim khoom tuag thiab CNC machinists hauv kev tsim khoom thiab kev tsim cov khoom lag luam. Thaum CAD muaj ntau txoj haujlwm uas tsis tas yuav koom nrog CAM, tib yam tsis tuaj yeem hais txog CAM, thiab feem ntau, CAM yog nyob ntawm CAD hnyav heev.
Qhov txawv ntawm CAD thiab CAM
CAD thiab CAM yog ob qho tib si ib feem ntawm tag nrho cov txheej txheem tseem ceeb uas raug xa mus rau hauv computer aided engineering (CAE). CADS thiab CAM muaj qhov zoo sib xws thiab lawv muab cov khoom hauv 2D lossis 3D. Ob leeg CAD thiab CAM pab hauv kev ua haujlwm sai thiab tsim cov qauv tsim uas yog lub tswv yim los ntawm tus kws tshawb fawb. Feem ntau ntawm cov tshuab CAM muaj inbuilt CAD software.
Qhov sib txawv loj ntawm CAD thiab CAM nyob rau hauv cov neeg siv kawg. Thaum CAM software feem ntau yog siv los ntawm tus kws tshaj lij, CAM yog siv los ntawm tus kws kho tshuab ua haujlwm. Cov machinists no txawj txawj heev thiab sib npaug rau ib tug computer engineer.
Summary
• CAD hais txog Computer Aided Design, hos CAM stands for Computer Aided Manufacture.
• CAD thiab CAM tau hloov pauv txoj kev tsim thiab tsim khoom.
• CAD thiab CAM muaj kev vam khom rau ib leeg.
